10 l-T'ine, 



Thego larvre fed on oak, pi iiicipally on the under cuticle of the leaves, and 

 when full-fed, spun up in small boat-shaped cocoons of silk, about -f-^ inch in length, 

 assimilating perfectly in colour to the surrounding surface of the bark on which 

 they were constructed, — a circumstance which rendered their detection vei y difficult 

 After the escape of the moths, which took place sometime about the middle of 

 July, the cocoons still retained their form and appearance. 



For the sake of close examination, one individual was kept without bark until 

 too late for its spinning a perfect cocoon, and at last it attached itself to the under- 

 side of a leaf \j the tail amongst a few threads, and there pupated much after the 

 manner of an Ephyra. 



The full-grown larva is but little more than three-eighths of an inch in length, 

 its body is rather stout in proportion, thickest at the third and fourth segments, 

 and tapered a little from the seventh to the anal extremity ; the head is full and 

 rounded, but of less bulk than the second segment ; the body is rounded on the 

 back and sides, and rather flattened beneath; it has three longitudinal rows- of 

 prominent wart-like tubercles on each side, i. e., six on each segment, bearing 

 fascicles of radiating hairs ; it has fourteen legs, the first ventral pair situated at 

 the eighth segment. 



The colour of the body is pale buff, sometimes partaking of aflesh tint ; the dorsal 

 stripe is yellowish or whitish flesh colour, very broad, and well-defined by a fine border 

 line of brownish -grey ; the sub-dorsal line is brownish-grey, but interrupted at the 

 segmental divisions ; all the tubercles are broadly ringed with this colour ; a 

 conspicuous blackish-grey blotch covers the back of the seventh segment, and 

 extends from one sub-dorsal line to the other ; there are indications of other 

 blotches of the same colour on the tenth and eleventh segments, but these are cut 

 in twain by the broad, cleai-, pale dorsal stripe travelling through and separating 

 them into a narrow dark mark on each side of the back ; the sides are flesh colour, 

 the spiracles are entirely hidden from observation by the numerous hairs which 

 diverge near them from the tubercles ; the ventral surface is pale flesh colour and 

 naked ; the head blackish-grey, the lobes narrowly margined in front with pale 

 flesh colour ; the hairs of the tubercles on the anterior segments are pale bi'own 

 mixed with a few of dark grey, and some few of them in front of the second seg- 

 ment, and especially on the third, are very long ; the tubercles on the rest of the 

 body are furnished with hairs of a paler yellowish cohiur; on the back of the 

 anterior part of the anal segment, issuing from each side, are a few hairs of extra 

 length, which converge and taper on each side to a fine point directed outwards in a 

 slightly downward curve, so that these two fine points of hair resemble a forked tail. 



The pupa is four lines long, including the cast larva skin adhering to its tail ; 

 it is not very stout, of ordinary shape, though the wing-cases are long in propor- 

 tion ; these last are reddish-brown in colour, the other parts very dark brown and 

 without much polish. — Id. 



Description of the larva of Eupithecia sxihciliata. — In the month of August, 

 1871, Mr. Sang, of Darlington, kindly sent me two living females of Eup. subciliata. 

 One of them was " in artieulo mortis " when they arrived, the other, which was very 

 lively, I placed under a large bell-glass with some sprigs of maple {Acer campestre) 

 in a vial of water.
